Answer:
-7,759.29 dollar
Step-by-step explanation:
cost of maintenance and operation
initial cost of $5500 x 20%
= 1100 Dollars
salvage value
initial cost of $5500 x 5%
= $275
pw = -5500-1100(p/a,17%,3) +275(p/f,17%,3)
pw = -5500-(1100*2.21) + (275*0.6244)
pw = -5500-2431+17.71
= -7759.29
so pw, that is present worth of new stations using internal MARR of 17% is -7759.29 dollars
